INTERNAL-COMBUSTION ENGINE.

Application nled April 28, 1924. Serial No. 709,370.

My invention, which is a continuation in part of application No. 422,753, filed Nov. 9, 1920, and since matured into Reissue Patent No. 16,909, March 20, 1928, re-

lates to cooling devices for internal combustion engines and it has for an object to provide apparatus of this character which shall be reliable in operation and which shall assure that cooling water shall not be- EO come admixed with oil in the engine casing. To cool the interior parts of an internal combustion engine, such as a piston, necessitates movable piping, which, in turn, requires articulated or telescopic joints.

With an engine of this type, it is desirable to have a closed casing in order to prevent loss orcontamination of oil. Also the conduit means must be of such a character to avoid the admixture of cooling water with the engine oil. Hence, I use telescopic piping connections providing for the inlet and outlet of cooling water to an engine piston, the telescopic connections being arranged within the engine casing; and each connection is provided with a communicating conduit leading through the engine casing, suitable packing being arranged between the conduits and the casing toprevent the es cape of oil. It is'fan object of my invention to provide' apparatus of this character which shall include alower piping member terminating within and at the bottom ont a pocket or box-like member protruding 1nwardly of the engine casing and open at one side through the wall ot the engine casing, suoli lower piping member being 'arranged to receive an upper piping member connected to a piston and the upper piping member passing through the top of the box. 4o or pocket member, across the latter, and y telescoping with the lower piping member, whereby water passing along the outside of the upper piping member may collect in the pocket. Y

A further object of my invention is to provide a telescopic plping connection wherein the outer pipe member terminates within a pocket or casing and the cooperating pipe member extends across the casing and enters the first piping member, packing being arranged between the cooperating pipe members and an adjustable packingv device being carried by the` pocket or box member and cooperating with the second 55 lpipe member, whereby the passageot duid outside of and along the second piping member beyond the box or pocket member is prevented.

These and other objects are accomplished by my lnvention as will be apparent from the following description taken in connection with the accompanying drawings, forming a part of this application, in which:

Fig. 1 is a fragmentary View, partly in section, showing my improved cooling arrangement applied to an engine;

Fig. 2 is a fragmentary detail view of one of the cooling devices; and,

Fig. 3 is a detail sectional View on a larger scale showing my improved type of telescopic connections.

Referring now to the drawings for a better understanding of my invention, in Fig. 1, I show an engine at 10 having a cylinder 11 within which fits a piston 12. The piston 12 is provided with an inlet cooling conxligction 13 and an outlet cooling connection The cooling connections 18 and 13a are identical in structure so that the desription of one is sufiicient for the purposes of my invention. Each cooling connection includes a lower pipe member 14 joined to a conduit 15' passing through the engine casing 16, a packed joint 17 surrounding the conduit to prevent leakage. The upper end of the pipe member 14 terminates within and at the bottom of a pocket or box member 18 inset with respect to the engine casing 16 and having an opening 19 to the outside. An upper pipe member 2() passes through the top 21 of the pocket or box member 18, across the latter, and: telescopes with the lower pipe member 14. Each u per pipe member 20 has an a propriate o set pipingj connection 22 wit respect to a piston to e cooled so that the inlet and outlet upper pipe members 20 may move with the piston.

The telescopic joint between the lower and upper pipe members 14 and 2() is packed toy prevent leakage of Water along the outside of the upper pipe member 20. To this end, 1 show a depending sleeve member 23 extending within the lower pipe member 14 and having an upper a'nge 24 adapted to be secured to the bottom 25 of the pocket or casing 18 by suitable screws 26. The casing yconstruction 23 surrounds the upper pipe member 20 and it is provided with a titi lower inwardly projecting Hangs 27 to support packing 28, the latter being compressed to the requisite degree of tightness by a gland nut structure at 30.` From Fig. 3, it will be noted that the packing 28 is of such a character as to oifer great resistance to the passage of water upwardly and outside of the upper pipe member 20.

As the telescopic piping connection is arranged within the engine casing, the upper pipe member 20 passes through the top 21 of the pocket or chamber 18 within the engine casing. It is essential to prevent even a thin film VVof water adhering to the upper pipe member 20 if contamination of engine oi is to be avoided. To this end, I show a novel form of packing which is capable of maintaining a tight joint with respect to an upper pipe member in a very durable manner. This packing construction includes a tubular member 31 surrounding the upper pipe member 20 and having a ball member 32 fitting aspherical seatv 33 in a lower cover member 34 secured to the top member 21. An upper cover member 35 is provided with a socket 36, which mates with the socket 33 and 'ts the ball portion 32, the cover members 34 f. and 35 being secured together in any suitable manner, as by the screws 37. rllhe lower cover member 34 is preferably provided with a. cylindrical recess 38 to receive .a cylindrical follower portion 39 carried b the upper cover member 35, packing 40 og any suitable type being arranged within the recess 38 and held with the proper degree of tightness by the follower portion 39 against the exterior of the ball portion 32. f 'lhe lower end of the tubular member 31 is connected to a packing housing 40', which contains packing 41 of any suitable type held with the ,requisite degree of tightness against the upper tubular member 201 by means ot a lower gland nut 42, the packing abutting against an upper, inwardlyprojecting annular shoulder 43 carried by the housing 41.

From the structure just described, it will be apparent that the packing 41 may be accurately centered with respect toan upper pipe member 20 without likelihood of such packing being worn in -an eccentric manner by the reciprocator motion of the upper piping member. 'l is result is largely due to the fact that the packing 41 is arranged at a considerable distance from the ball-andsocket supporting connection for the tubular member 31, whereby only small lateral pressures are necessary in order to obtain concentric adjustment of the packing with respect to an upper piping member 20.

ln operation, cooling water enters a piston 12 through the supply cgnnection 13 and is discharged through the connection 13B. The passage or" water upwardly and outside et the upper piping member 20 is monaco largely prevented by packing 28 surrounding the upper piping member 20 and supported by the bottom of the pocket 0r box member 18. Experience shows that, however well made such packing may be; it is neverthelessy very difficult to prevent the passage of a thin film of water along with the piping member 20 during this upward movement. Accordingly, therefore, l provide an upper packing 41 arranged about the upper pipe member 20 and having a universal supporting connection with respect to .the top of the pocket or box structure 18, such packing being suspended 'from l the ball member of the joint by a tubular structure so that only slight lateral forces are necessary to secure proper adjustment of the packing to assume a relation concentric'with the tubular member 20, whereby durability of the packing is greatly enhanced.

From the foregoing, it will be apparent that l have provided a telescopic type of piping connection which assures the prevention of cooling water for an engine piston from entering the interior of the engine casing, thereby avoiding the contamination of lubricating oil within the casing. Any films ofA water adhering to the upper pipe members 20 are, therefore, wiped ofi by the packing constructions 41, such water and.. possible traces of oil collecting' in the chambers 18 Jfrom which the collections may be drained from time to time by opening the drainage openings 44. rllhe packing 41 also serves to prevent leakage of oil from the engine casing to the pocket. The -opening 19 provides a window through which the condition of the packing maybe observed and through which adjustments of the gland nuts may bemade. l

While ll have shown my invention in but one form, it will be obvious to those skilled in the art thatv it is not so limited, but is susceptible ot various other changes and modifications without departing from the spirit thereof, and l desire, therefore, that l only such limitations shall be placed thereupon as are imposed by theprior art or as are specifically set forth inthe appended Having thus described the invention what l claim as new and desire to secure by Letters Patent is:
